You are using a CAShapeLayer
. If your fillColor
and your strokeColor
are both opaque (alpha 1.0), you can simply set the layer's backgroundColor
to fill those pixels that are within the layer's bounds but outside of its stroked and filled path.
My test code:
@implementation ViewController {
CAShapeLayer *layer;
}
- (void)viewDidLoad {
[super viewDidLoad];
layer = [CAShapeLayer layer];
layer.path = [UIBezierPath bezierPathWithOvalInRect:CGRectMake(50, 50, 250, 250)].CGPath;
layer.fillColor = [UIColor yellowColor].CGColor;
layer.strokeColor = [UIColor whiteColor].CGColor;
layer.lineWidth = 4;
layer.backgroundColor = [UIColor purpleColor].CGColor;
[self.view.layer addSublayer:layer];
}
- (void)viewDidLayoutSubviews {
layer.frame = self.view.bounds;
}
@end
Result:
